DETAILED DESCRIPTION

The following description is presented to enable any person skilled in the art to make and use the present disclosure and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the present disclosure is not limited to the embodiments shown but is to be accorded the widest scope consistent with the claims.

The terminology used herein is to describe particular exemplary embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context expressly indicates otherwise. It will be further understood that the terms “comprise,” “comprises,” and/or “comprising,” “include,” “includes,” and/or “including,” when used in the present disclosure, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

These and other features, and characteristics of the present disclosure, as well as the methods of operation and functions of the related elements of structure and the combination of parts and economies of manufacture, may become more apparent upon consideration of the following description with reference to the accompanying drawings, all of which form a part of the present disclosure. It is to be expressly understood, however, that the drawings are for the purpose of illustration and description only and are not intended to limit the scope of the present disclosure. It is understood that the drawings are not to scale.

It will be understood that the term “system,” “engine,” “unit,” and/or “module” used herein are one method to distinguish different components, elements, parts, sections, or assemblies of different levels in ascending order. However, the terms may be displaced by other expressions if they achieve the same purpose.

It will be understood that when a unit, engine, or module is referred to as being “on,” “connected to,” or “coupled to,” another unit, engine, or module, it may be directly on, connected or coupled to, or communicate with the other unit, engine, or module, or an intervening unit, engine, or module may be present, unless the context clearly indicates otherwise. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

The flowcharts used in the present disclosure illustrate operations that systems implement according to some embodiments of the present disclosure. It is to be expressly understood, the operations of the flowcharts may be implemented not in order. Conversely, the operations may be implemented in inverted order, or simultaneously. Moreover, one or more other operations may be added to the flowcharts. One or more operations may be removed from the flowcharts.

Moreover, while the systems and methods described in the present disclosure are described primarily regarding a bicycle sharing service, it should also be understood that they are merely exemplary embodiments. The systems or methods described in the present disclosure may apply to any other kind of economic sharing service that transfers a usufruct from one to another in an online rental transaction. For example, the systems or methods of the present disclosure may apply to physical asset renting and/or a labor service. The physical asset may include real estate (e.g., a hotel, a room, or an apartment), vehicles (e.g., a car, a bicycle, an electric bicycle, a bus, a hot-air balloon, or an airplane), goods (e.g., clothes, an umbrella, a charger, or a microphone), etc. The labor service may include pet adoption, housekeeping, designated driving, etc. The application of the systems or methods of the present disclosure may include a web page, a plug-in for a browser, a client terminal, a custom system, an internal analysis system, an artificial intelligence robot, or the like, or any combination thereof.

The positioning technology used in the present disclosure may be based on a global positioning system (GPS), a global navigation satellite system (GLONASS), a compass navigation system (COMPASS), a Galileo positioning system, a quasi-zenith satellite system (QZSS), a wireless fidelity (WiFi) positioning technology, or the like, or any combination thereof. One or more of the above positioning systems may be used interchangeably in the present disclosure.

It should be noted that the bicycle sharing service is a new form of service rooted only in post-Internet era. It provides technical solutions to users and service providers that could raise only in the post-Internet era. In the pre-Internet era, when a user needs to rent a bicycle in a bicycle rental shop, the bicycle request and acceptance occur only between the user and a shopkeeper of the bicycle rental shop who meet each other at a physical place. Through the Internet (and/or other types of network technology like Bluetooth), the bicycle sharing service, however, allows a user of the service to acquire a location of a bicycle accurately and rent a bicycle anywhere and anytime. It also allows the user to park the bicycle in any area where the parking of the bicycle is allowed. Therefore, through the Internet, a bicycle sharing system may provide a more convenient transaction platform for users and service providers that may never meet in the settings of the traditional, pre-Internet bicycle service.

The present disclosure relates to systems and methods for unlocking a lock in security systems. The systems and methods may be implemented by a server, workstation, a lock (e.g., a lock in a bicycle, a lock in a vehicle, a lock in a door to a secured place), and/or a terminal device. For example, the server may obtain a service request from a terminal device and provide a reference unlocking password that may be used to unlock a lock. After receiving the reference unlocking password, a requestor may enter the password via the terminal device or an input device of the lock. The lock may determine whether a password included in the input is consistent with a pre-stored password in the lock. According to a result of the determination that the password included in the input is consistent with the pre-stored password, the lock may unlock the lock. Further, the lock may determine service information associated with the service request and transmit the service information to the server.

FIG. 1 is a schematic diagram illustrating an exemplary security system 100 according to some embodiments of the present disclosure. The security system 100 may include a server 110, a network 120, one or more terminal devices 130, a device 140, a storage 150, a positioning device 160, and a lock 170. The security system 100 may secure the device 140 by the lock 170 by implementing the methods and/or processes disclosed in the present disclosure. In some embodiments, the device 140 to be secured may be a bicycle in a bicycle sharing system. The bicycle sharing system may provide a bicycle sharing service allowing a user to use a bicycle for a ride. When the user finishes the ride and wants to return the bicycle, the user may leave the bicycle in an area where the parking of the bicycle is allowed. The bicycle may then be ready for a next user.

The server 110 may communicate with the terminal device 130, the device 140, and/or the lock 170 to provide various functionalities of the security system 100. In some embodiments, the server 110 may receive a request associated with the device 140 from the terminal device 130 via, for example, the network 120. For example, the server 110 may receive a request to unlock the device 140 from the terminal device 130 via, for example, the network 120. As another example, the device 140 may be a bicycle in a bicycle sharing system and the request may be a service request to borrow (or rent) the bicycle. The service request may include order information relating to the ride and/or the bicycle, including, for example, a bicycle type, a departing place, a destination, mileage, a route, or the like, or any combination thereof. The service request may also include the information relating to the user (e.g., the user account information) and/or the terminal device 130 (e.g., the location of the terminal device 130).

The server 110 may also transmit information to the terminal device 130, the device 140, and/or the lock 170. For instance, the server 110 may transmit to a device 140 and/or the lock 170 an instruction to lock the device 140, an instruction to unlock the device 140, and/or the information related to the device 140 (e.g., the information indicating whether the device 140 is locked). In some embodiments, the device 140 may be a bicycle in a bicycle sharing system. The server 110 may determine one or more bicycles in response to the service order received from the terminal device 130 and transmit the information relating to the one or more bicycles to the terminal device 130, including, for example, the locations of the one or more bicycles, the fees for the ride (e.g., the total fees for the ride, the hourly rate for the ride), or the like, or a combination thereof.

The server 110 may also determine a hotspot area based on historical data obtained from the terminal device 130, the bicycle, and/or the storage 150. The hotspot area may be an area where bicycles are in high demand. The historical data may include the number of searches for a bicycle in an area. The historical data may also include data relating to historical service orders (e.g., the number of times that the bicycles have been used in an area). The historical data may further include information provided by users via the terminal devices 130 (e.g., advice to place more bicycles in some area submitted by users). The server 110 may also provide a service fee management. The server 110 may determine the cost of a ride based on a monthly membership, a quarterly membership, a season (e.g., spring, summer) membership, an annual membership, or fees per ride.

In some embodiments, the server 110 may be a single server or a server group. The server group may be a centralized server group connected to the network 120 via an access point or a distributed server group connected to the network 120 via one or more access points, respectively. In some embodiments, the server 110 may be locally connected to the network 120 or in remote connection with the network 120. For example, the server 110 may access information and/or data stored in the terminal device 130, the device 140, and/or the storage 150 via the network 120. As another example, the storage 150 may serve as backend data storage of the server 110. In some embodiments, the server 110 may be implemented on a cloud platform. Merely by way of example, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an inter-cloud, a multi-cloud, or the like, or any combination thereof.

In some embodiments, the server 110 may include a processing engine 112. The processing engine 112 may process information and/or data associated with a service request to perform one or more functions in the present disclosure. For example, the processing engine 112 may obtain a service request from the terminal device 130 and transmit unlock information (e.g., an unlocking password) to the terminal device 130. In some embodiments, the processing engine 112 may include one or more processing units (e.g., single-core processing engine(s) or multi-core processing engine(s)). Merely by way of example, the processing engine 112 may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction-set processor (ASIP), a graphics processing unit (GPU), a physics processing unit (PPU), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction-set computer (RISC), a microprocessor, or the like, or any combination thereof.

The network 120 may facilitate exchange of information and/or data. In some embodiments, one or more components of the security system 100 (e.g., the server 110, the terminal device 130, the device 140, the storage 150, or the lock 170) may transmit information and/or data to another component(s) in the security system 100 via the network 120. For example, the server 110 may access and/or obtain data of a plurality of devices 140 from the storage 150 via the network 120. As another example, the server 110 may transmit a message indicating whether the device 140 is locked to the terminal device 130 via the network 120. As yet another example, the positioning device 160 may transmit positioning information to the terminal device 130 via the network 120. In some embodiments, the network 120 may be any wired or wireless network, or combination thereof. Merely by way of example, the network 120 may include a cable network, a wireline network, an optical fiber network, a telecommunications network, an intranet, an Internet, a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a metropolitan area network (MAN), a wide area network (WAN), a public telephone switched network (PSTN), a Bluetooth network, a ZigBee network, a near field communication (NFC) network, or the like, or any combination thereof. In some embodiments, the network 120 may include one or more network access points. For example, the network 120 may include wired or wireless network access points such as base stations and/or internet exchange points 120-1, 120-2, . . . , through which one or more components of the security system 100 may be connected to the network 120 to exchange data and/or information.

In some embodiments, a user may be an owner of the terminal device 130. The terminal device 130 may receive input from the user and transmit the information relating to the input to the server 110 via the network 120. The terminal device 130 may also receive information from the server 110 via the network 120. For example, the terminal device 130 may receive input from the user relating to the device 140 to the server 110, receive a service confirmation, and/or information or instructions from the server 110. Merely by way of example, a user may input a request for maintenance service when he or she fails to lock the device 140. The terminal device 130 may be configured to transmit the request for maintenance service to the server 110. In some embodiments, the device 140 may be a bicycle in a bicycle sharing system. The terminal device 130 may be configured to transmit a service request to the server 110 for searching for bicycles near the location of the terminal device 130. The server 110 may determine one or more bicycles (e.g., the locations of the bicycles, number of the bicycles) near the location of the terminal device 130 according to and in response to the service request. The server 110 may also transmit information relating to the determined one or more bicycles to the terminal device 130 via the network 120. The information of the determined one or more bicycles may be displayed on the terminal device 130 associated with an electronic map. The terminal device 130 may receive input from the user indicating a selected bicycle from the bicycles displayed on the terminal device 130, which may be transmitted to the server 110. The terminal device 130 may also provide a walking navigation for guiding the user to the location of the selected bicycle. As another example, the terminal device 130 may receive input from the user for reserving a bicycle and transmit the information to the server 110. As yet another example, the terminal device 130 may transmit feedback information provided by the user to the server 110. The feedback information may include the status of the bicycle (e.g., whether any part of the bicycle needs to be repaired), improvement suggestions, etc.

One of ordinary skill in the art would understand that when an element of the security system 100 performs, the element may perform through electrical signals and/or electromagnetic signals. For example, when a terminal device 130 processes a task, such as making a determination, unlocking a device 140, the terminal device 130 may operate logic circuits in its processor to process such task. When the terminal device 130 transmits out a query (e.g., information relating to a location of a device 140) to the server 110, a processor of the terminal device 130 may generate electrical signals encoding the query. The processor of the terminal device 130 may then transmit the electrical signals to an output port. If the terminal device 130 communicates with the server 110 via a wired network, the output port may be physically connected to a cable, which further transmits the electrical signal to an input port of the server 110. If the terminal device 130 communicates with the server 110 via a wireless network, the output port of the terminal device 130 may be one or more antennas, which convert the electrical signals to electromagnetic signals. Similarly, a device 140 and/or the lock 170 may process a task through operation of logic circuits in its processor, and receive an instruction and/or service order from the server 110 via electrical signals or electromagnet signals. Within an electronic device, such as the terminal device 130, the device 140, the lock 170, and/or the server 110, when a processor thereof processes an instruction, transmits out an instruction, and/or performs an action, the instruction and/or action is conducted via electrical signals. For example, when the processor retrieves data (e.g., a plurality of user profiles) from a storage medium (e.g., the storage 150), it may transmit out electrical signals to a reading device of the storage medium, which may read structured data in the storage medium. The structured data may be transmitted to the processor in the form of electrical signals via a bus of the electronic device. Here, an electrical signal may refer to one electrical signal, a series of electrical signals, and/or a plurality of discrete electrical signals.

As yet another example, as illustrated in Table 4, for the plurality of unlocking passwords, the processing module 520 may define a plurality of valid periods respectively. As used herein, “valid period” refers to a period within which a corresponding password can be used to unlock the bicycle. The valid period may be default settings of the bicycle sharing system or may be adjustable in different situations.

TABLE 4 An exemplary relationship between passwords and valid periods Lock Serial Number Password Valid Period Lock001 12HJB3 12:00-12:30 89TYVD 12:30-13:00 108YZ6 13:00-13:30 GXY930 13:30-14:00 Lock002 . . . . . . . . . . . . . . .

In some embodiments, after obtaining a service request, the processing module 520 may determine a reference unlocking password based on the bicycle identification information (e.g., the bicycle serial number) included in the service request. The processing module 520 may determine a specific lock serial number based on the bicycle serial number according to Table 1 and determine the reference unlocking password based on the specific lock serial number according to Table 2, Table 3, or Table 4. For example, the processing module 520 may determine the reference unlocking password corresponding to the specific lock serial number according to Table 2. As another example, according to Table 3, the processing module 520 may randomly select an unlocking password corresponding to the specific lock serial number as the reference unlocking password. As yet another example, according to Table 4, the processing module 520 may determine a valid period within which the service request is initiated and determine an unlocking password corresponding to the specific lock serial number based on the valid period as the reference unlocking password.

In some embodiments, the processing module 520 may further determine a relationship (e.g., Table 5) between requestors and unlocking passwords based on the user information (e.g., the user identity associated with the terminal device 130) included in the service request.

TABLE 5 An exemplary relationship between users and passwords Requestor Password Requestor 1 135780 Requestor 2 237051 . . . . . .

In some embodiments, when a service transaction associated with the service request is completed, the processing module 520 may update the relationship (e.g., Table 2, Table 3) between the lock serial numbers and the unlocking passwords. For example, assuming that the service request is associated with bicycle “JA546” corresponding to a lock serial number “Lock001.” As illustrated in Table 2, when the service transaction associated with the service request is completed, the processing module 520 may delete the unlocking password “135780” (or mark the unlocking password “135780” as suspended or invalid) corresponding to the lock serial number “Lock001” and determine an updated unlocking password (e.g., “349062” illustrated in Table 6).

TABLE 6 An exemplary updated relationship between lock serial numbers and unlocking passwords Lock Serial Number Password Lock001 349062 Lock002 237051 . . . . . .

As another example, also assuming that the service request is associated with bicycle “JA546” corresponding to the lock serial number “Lock001.” As illustrated in Table 3, when the service transaction associated with the service request is completed, the processing module 520 may delete the unlocking password “12HJB3” (or mark the unlocking password “12HJB3” as suspended or invalid) corresponding to the lock serial number “Lock001” and update the relationship between lock serial numbers and unlocking passwords as illustrated in Table 7. In this example, when all unlocking passwords corresponding to a specific lock serial number are deleted (or marked as suspended or invalid), the processing module 520 may determine and/or maintain a new table indicating the relationship between lock serial numbers and unlocking passwords.

TABLE 7 An exemplary updated relationship between lock serial numbers and unlocking passwords Lock Serial Number Password Lock001 89TYVD 108YZ6 GXY930 . . . Lock002 654321 120987 . . . . . . . . .

In some embodiments, the processing module 520 may update the relationship between the serial numbers and the unlocking passwords. In some embodiments, the processing module 520 may update the relationship periodically. For example, as illustrated in Table 4, for a specific lock serial number, an unlocking password corresponds to a valid period. The plurality of valid periods may be determined by segmenting a cycle period (e.g., 2 hours). At the end of the cycle period, the processing module 520 may determine a group of updated unlocking passwords.

In some embodiments, during the ride process associated with the service request and/or after the service transaction associated with the service request is completed, the processing module 520 may determine billing information based on the service information associated with the service request.

In some embodiments, the processing module 520 may analyze the user identification information (e.g., the IC card information, the iris information, the fingerprint information) associated with the requestor and determine an unlocking instruction based on the analysis result. For example, the processing module 520 may compare the fingerprint information with reference fingerprint information that has been registered to the bicycle sharing system. According to a result of the determination that the fingerprint information is consistent with the reference fingerprint information, the processing module 520 may determine an unlocking instruction. According to a result of the determination that there is no corresponding reference fingerprint information which is consistent with the fingerprint information, the processing module 520 may generate a notification to notify the requestor to register to the bicycle sharing system.

In some embodiments, the processing module 520 may process the maintenance information and determine whether the bicycle needs repair. For example, the processing module 520 may determine whether the residual capacity of the power supply 460 is lower than a threshold. According to a result of the determination that the residual capacity is lower than the threshold, the processing module 520 may provide a notification to notify a maintenance worker to detect the power supply 460. As another example, the processing module 520 may compare the time information associated with the bicycle with standard time information and calibrate the timing in the bicycle.

The transmission module 530 may be configured to transmit information and/or data associated with the service request, the user identification information, and/or the maintenance information to the bicycle and/or the terminal device 130. The transmission module 530 may transmit the information and/or data via one or more messages using any suitable communication protocol (e.g., the Hypertext Transfer Protocol (HTTP), Address Resolution Protocol (ARP), Dynamic Host Configuration Protocol (DHCP), File Transfer Protocol (FTP)).

In some embodiments, the transmission module 530 may transmit a reference unlocking password corresponding to the service request to the terminal device 130.

In some embodiments, the transmission module 530 may transmit one or more unlocking passwords to the bicycle (e.g., the lock 170) to be stored according to Tables 1-4 and 6-7. For example, as described in connection with Table 2 and Table 6, when a prior service transaction associated with a prior service request is completed, the processing module 520 may update the relationship between the lock serial numbers and the unlocking passwords. Further, the transmission module 530 may transmit the updated unlocking password to the bicycle. As another example, as described in connection with Table 3 and Table 7, when all prior unlocking passwords are deleted or marked as invalid, the processing module 520 may determine and/or maintain a new table indicating the relationship between lock serial numbers and unlocking passwords. Further, the transmission module 530 may transmit the updated unlocking passwords corresponding to the bicycle to the bicycle. As a further example, as described in connection with Table 4, the processing module 520 may periodically update the relationship between the lock serial numbers and unlocking passwords. Further, the transmission module 530 may periodically transmit the updated unlocking passwords to the bicycle.

In some embodiments, the transmission module 530 may transmit the billing information to the terminal device 130.

In some embodiments, the transmission module 530 may transmit an unlocking instruction to the bicycle. For example, according to a result of the determination that the fingerprint information is consistent with the reference fingerprint information, the transmission module 530 may transmit the unlocking instruction to the lock 170.

The modules in the processing engine 112 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined into a single module, and any one of the modules may be divided into two or more units. For example, the obtaining module 510 and the transmission module 530 may be combined into a single module which may both obtain a service request from the terminal device 130 and transmit information and/or data (e.g., the reference unlocking password, the billing information) associated with the service request to the terminal device 130. As another example, the processing engine 112 may include a storage module (not shown) used to store information and/or data (e.g., the bicycle identification information, the relationships among bicycle serial numbers, lock serial numbers, and/or unlocking passwords) associated with the service request(s).

FIG. 6 is a block diagram illustrating an exemplary lock according to some embodiments of the present disclosure. The lock 170 may include a matching module 610, a lock information determination module 620, a service information determination module 630, and a storage module 640.

The matching module 610 may be configured to determine whether an input obtained from the terminal device 130 satisfies an unlocking condition. In some embodiments, the matching module 610 may determine whether a password included in the input from the user (via the terminal device 130 or an input device of the bicycle) is consistent with a pre-stored password in the bicycle (e.g., the lock 170). As described in connection with FIG. 5, the transmission module 530 may transmit one or more unlocking passwords to the bicycle. The one or more unlocking passwords may be stored in a storage device (e.g., the storage module 640) in the lock 170.

In some embodiments, as illustrated in Table 2 and Table 6, the bicycle may pre-store one password. The matching module 610 may match the password included in the input with the pre-stored password. According to a result of the determination that the password included in the input is consistent with the pre-stored password in the bicycle, the control component 420 may actuate the lock 170 to unlock the bicycle.

In some embodiments, as illustrated in Table 3 and Table 7, the bicycle may pre-store a plurality of candidate passwords. The matching module 610 may match the password included in the input with the plurality of candidate passwords respectively. According to a result of a determination that the password included in the input is consistent with one of the plurality of candidate passwords, the control component 420 may actuate the lock 170 to unlock the bicycle.

In some embodiments, as illustrated in Table 4, the bicycle may pre-store a plurality of candidate passwords corresponding to a plurality of valid periods. The matching module 610 may determine a time point (e.g., 12:10) when the input is obtained and identify a target unlocking password corresponding to a valid period (e.g., 12:00-12:30) including the time point. Further, the matching module 610 may compare the password included in the input with the target unlocking password and according to a result of the determination that the password included in the input is consistent with the target unlocking password in the bicycle, the control component 420 may actuate the lock 170 to unlock the bicycle.

In some embodiments, according to a result of the determination that the password included in the input is not consistent with the pre-stored password in the bicycle, the matching module 610 may provide a notification to the terminal device 130 to notify the requestor that there may be an error in the input. For example, the matching module 610 may transmit a message to the terminal device 130. As another example, the matching module 610 may provide a popup notification via an application installed on the terminal device 130. As a further example, the matching module 610 may actuate the display 450 to display a tip screen (e.g., a highlight, a twinkling). As a still further example, the matching module 610 may actuate an audio device (not shown) on the bicycle to provide an audio notice.

The lock information determination module 620 may be configured to determine lock information associated with the service request. The lock information may include lock identification information (e.g., a lock serial number), a time point when the lock 170 is unlocked (also referred to as an “unlocking time point”), a time point when the lock 170 is locked (also referred to as a “locking time point”), etc.

In some embodiments, the lock information determination module 620 may determine the unlocking time point and the locking time point by a clock (not shown) integrated into the lock 170. In some embodiments, the lock information may further include the bicycle identification information (e.g., the bicycle serial number), basic information (e.g., bicycle type, bicycle age), maintenance information (e.g., power information) associated with the bicycle, etc.

The service information determination module 630 may be configured to determine service information based on the lock information. The service information may include the lock information, a user identity associated with the terminal device 130, a start location associated with the service request, a destination associated with the service request, etc. In some embodiments, the service information may further include a travel time from the start location to the destination (or the location the user stops), a travel route associated with the start location and/or the destination, a predicted fee associated with the service request, etc.

In some embodiments, the service information determination module 630 may further transmit the service information to the server 110. In some embodiments, the service information determination module 630 may determine whether a connection between the bicycle and the server 110 is established. According to a result of the determination that the connection is not established, the service information determination module 630 may store the service information in the bicycle, and when the connection is established, the service information determination module 630 may transmit the service information to the server 110.

The storage module 640 may be configured to store any information and/or data associated with the service request, the lock information, the service information, etc. In some embodiments, the storage module 640 may store the unlocking password(s) obtained from the server 110. For example, as described in connection with FIG. 5, the transmission module 530 may transmit one or more unlocking passwords to the lock 170. The one or more unlocking passwords may be stored in the storage module 640. In some embodiments, the storage module 640 may store the service information based on a result of the determination that the connection between the bicycle and the server 110 is not established.

The modules in the lock 170 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined into a single module, and any one of the modules may be divided into two or more units. For example, the lock information determination module 620 and the service information determination module 630 may be combined into a single module which may both determine the lock information and the service information.

FIG. 7 is a flowchart illustrating an exemplary process for unlocking a bicycle according to some embodiments of the present disclosure. In some embodiments, the process 700 may be executed by the bicycle sharing system. For example, the process 700 may be implemented as a set of instructions (e.g., an application) stored in the ROM 230 or the RAM 240. The processor 220 and/or the modules in FIG. 5 or FIG. 6 may execute the set of instructions and, when executing the instructions, it may be configured to perform the process 700. The operations of the illustrated process 700 presented below are intended to be illustrative. In some embodiments, the process 700 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 700 as illustrated in FIG. 7 and described below is not intended to be limiting.

In 710, the server 110 (e.g., the obtaining module 510 in the processing engine 112) may obtain a service request associated with a bicycle (e.g., the bicycle) from the terminal device 130 via the network 120. The service request may be a request for using a transportation service associated with the bicycle. The service request may include user information (e.g., a username, an identity card number, a user identity associated with the terminal device 130) associated with a requestor, bicycle identification information (e.g., a bicycle serial number) of the bicycle, etc.

In some embodiments, the requestor may initiate the service request by scanning an identity code (e.g., a QR code, a barcode) on the bicycle (e.g., a handlebar, frame, or lock) via the terminal device 130. The terminal device 130 may obtain the bicycle identification information according to the identity code. The terminal device 130 may also transmit the service request including the bicycle identification information to the server 110. In some embodiments, the requestor may manually input the bicycle identification information (e.g., the bicycle serial number) via the terminal device 130. The terminal device 130 may generate a service request including the bicycle identification information and transmit the service e request to the server 110 via the network 120.

In some embodiments, the requestor may initiate the service request via a wireless connection between the terminal device 130 and the bicycle. The wireless connection may include a short-range communication such as a Bluetooth connection, a ZigBee connection, a hotspot connection, a WiFi connection, or the like, or a combination thereof. For example, the bicycle (e.g., the communication port 440 in the lock 170) may broadcast a wireless signal within a predetermined range (e.g., a range within a certain radius (e.g., 5 m, 10 m, 20 m, 100 m, 500 m, 1 km) from the bicycle. The terminal device 130 within the range may detect the wireless signal and establish the wireless connection between the terminal device 130 and the bicycle. After establishing the wireless connection, the terminal device 130 may obtain the bicycle identification information (e.g., the bicycle serial number) of the bicycle and transmit the service request including the bicycle identification information to the server 110 via the network 120.

In some embodiments, when the requestor intends to initiate a service request, there may be a plurality of bicycles nearby. As used herein, “nearby” refers to that a distance between a bicycle and the terminal device 130 is less than a threshold (e.g., 10 m, 50 m, 100 m, 500 m). In this situation, the plurality of bicycles may broadcast a plurality of wireless signals. The terminal device 130 may determine a plurality of intensities of the plurality of wireless signals and accordingly determine a plurality of distances between the bicycles and the terminal device 130 based on the intensity of the individual signals. For example, the higher the intensity is, the shorter the distance between the bicycle and the terminal device 130 may be. The terminal device 130 may identify one or more bicycles with distance(s) less than a threshold (e.g., 8 m, 10 m). The terminal device 130 may automatically select one (e.g., one with the shortest distance, a random one) from the one or more bicycles. Alternatively or additionally, the user may select one from the one or more bicycles displayed on the terminal device 130. The terminal device 130 may also establish the wireless connection between the selected bicycle and the terminal device 130.

In some embodiments, after the wireless connection between the bicycle and the terminal device 130 is established, the bicycle may specify a connection permission associated with the wireless signal. Under the connection permission, any other terminal device cannot establish a wireless connection with the bicycle.

In some embodiments, the bicycle may include an ON/OFF switch (e.g., an ON/OFF button) for turning on or off the wireless signal on the bicycle. When a period within which no terminal device establishes a wireless connection with the bicycle is larger than a threshold (e.g., 30 minutes, 1 hour, 2 hours), the bicycle may set the mode of the bicycle (e.g., the lock 170) to a dormant mode. When a requestor intends to initiate a service request, the requestor may put the ON/OFF swith to the ON position, and the wireless connection between the terminal device 130 and the bicycle may be established.

In 720, the server 110 (e.g., the transmission module 530 in the processing engine 112) may transmit a reference unlocking password associated with the service request to the terminal device 130. For example, the server 110 may transmit a reference unlocking password to the terminal device 130 via the network 120.

In some embodiments, the server 110 (e.g., the processing module 520 in the processing engine 112) may determine the reference unlocking password to be transmitted to the terminal device 130 according to the bicycle identification information (e.g., the bicycle serial number) included in the service request. The server 110 may determine the lock serial number based on the bicycle serial number (e.g., according to Table 1) and determine the reference unlocking password based on the lock serial number (e.g., according to Table 2, Table 3, or Table 4). For example, the server 110 may determine the reference unlocking password corresponding to the specific lock serial number according to Table 2. Alternatively or additionally, according to Table 3, the server 110 may randomly select an unlocking password corresponding to the specific lock serial number as the reference unlocking password. Alternatively or additionally, according to Table 4, the server 110 may determine a valid period within which the service request is initiated and determine an unlocking password corresponding to the lock serial number based on the valid period as the reference unlocking password.

In 730, the bicycle (e.g., the matching module 610 in the lock 170) may obtain an input associated with the terminal device 130. As used herein, the input may refer to a manual input from a requestor, an instruction from the terminal device 130, etc. For example, the bicycle may obtain a manual input including a password by the requestor via the terminal device 130 or an input device (e.g., a keyboard, a virtual keyboard) on the bicycle. As another example, the bicycle may obtain an unlocking instruction including a password from the terminal device 130 via the wireless connection between the bicycle and the terminal device 130.

In 740, the bicycle (e.g., the matching module 610 in the lock 170) may determine whether the input satisfies an unlocking condition relating to the reference unlocking password. For example, the bicycle may determine whether the password included in the input is consistent with a pre-stored password in the bicycle. If the bicycle determines that the password included in the input is consistent with the pre-stored password in the bicycle, the bicycle may determine that the input satisfies the unlocking condition. On the other hand, if the bicycle determines that the password included in the input is inconsistent with the pre-stored password in the bicycle, the bicycle may determine that the input does not satisfy the unlocking condition. The pre-stored password may be obtained from the server 110. For example, the bicycle (e.g., the matching module 610) may receive the password from the server 110 via the network 120 and store the password in its storage device.

In some embodiments, as described in connection with Table 2 and Table 6, when a prior service transaction associated with a prior service request is completed, the server 110 may generate (or determine) an updated unlocking password and transmit the updated unlocking password to the bicycle to be stored via, for example, the network 120. The bicycle may determine whether the password included in the input in a next transaction is consistent with the updated password obtained from the server 110.

In some embodiments, as described in connection with Table 3 and Table 7, the server 110 may transmit a plurality of candidate passwords to the bicycle. The bicycle may determine whether the password included in the input from the user (via the terminal device 130 or an input device of the bicycle) is consistent with one of the plurality of candidate passwords obtained from the server 110.

In some embodiments, as described in connection with Table 4, the bicycle may pre-store a plurality of candidate passwords, which correspond to a plurality of valid periods. The bicycle may determine a time point (e.g., 12:10) when the input is obtained and identify a target unlocking password corresponding to a valid period (e.g., 12:00-12:30) including the time point. Further, the bicycle may determine whether the password included in the input is consistent with the target unlocking password.

According to a result of the determination that the input does not satisfy the unlocking condition, the bicycle (e.g., the matching module 610 in the lock 170) in 790 may provide a notification to the terminal device 130 to notify the requestor that there may be an error. For example, the bicycle may transmit a message indicating “password may be wrong” to the terminal device 130. Alternatively or additionally, the bicycle may actuate the display 450 to display a tip screen (e.g., a highlight, a twinkling). Alternatively or additionally, the bicycle may actuate an audio device (not shown) on the bicycle to provide an audio notice.

According to a result of the determination that the input satisfies the unlocking condition, the bicycle (e.g., the control component 420) in 750 may actuate the lock 170 to unlock the bicycle. For example, the matching module 610 may generate an unlocking instruction and transmit the unlocking instruction to the control component 420. The control component 420 may control the lock 170 to unlock the bicycle. After the bicycle is unlocked, the bicycle and the terminal device 130 may be paired, and other terminal devices cannot establish any connection with the bicycle until a service transaction associated with the service request is completed or the connection between the terminal device 130 and the bicycle is terminated.

In some embodiments, as described in connection with Table 2 and Table 6, according to a result of the determination that the input satisfies the unlocking condition, the bicycle may delete the pre-stored password or mark the password as invalid or suspended. After a service transaction associated with the service request is completed, the server 110 may transmit an updated password to the bicycle to be stored for a next service request.

In some embodiments, as described in connection with Table 3 and Table 7, according to a result of the determination that the input satisfies the unlocking condition, the bicycle may delete a specific candidate password that is consistent with the password included in the input or mark the specific candidate password as invalid or suspended. After one or more (or all) candidate unlocking passwords in the bicycle are deleted or marked as invalid or suspended, the server 110 may transmit a plurality of updated candidate passwords to the bicycle to be stored.

In some embodiments, as described in connection with Table 4, according to a result of the determination that the input satisfies the unlocking condition, the bicycle may delete the target unlocking password with the valid period including the time point when the input is obtained or mark the target unlocking password as invalid or suspended.

In 760, the bicycle (e.g., the lock information determination module 620) may determine lock information associated with the lock 170. The lock information may include lock identification information (e.g., a lock serial number), a time point when the lock 170 is unlocked, a time point when the lock 170 is locked, etc. In some embodiments, the lock information may further include the bicycle identification information (e.g., the bicycle serial number), basic information (e.g., bicycle type, bicycle age), maintenance information (e.g., power information) associated with the bicycle, etc.

In 770, the bicycle (e.g., the service information determination module 630) and/or the terminal device 130 may determine service information. The service information may include the lock information, a user identity associated with the terminal device 130, a start location associated with the service request, a destination associated with the service request, etc. The bicycle may determine the start location and/or the destination by the positioning component 430. The terminal device 130 may determine the start location and/or the destination by a GPS device of the terminal device 130. In some embodiments, the service information may further include a travel time from the start location to the destination (or the location the user stops), a travel route associated with the start location and/or the destination, a predicted fee associated with the service request, etc.

In 780, the bicycle (e.g., the service information determination module 630 or the communication port 440) and/or the terminal device 130 may transmit the service information to the server 110. In some embodiments, when the lock 170 is unlocked, the bicycle and/or the terminal device 130 may transmit start service information (e.g., the time point when the lock 170 is unlocked, the lock identification information, the start location associated with the service request, the user identity associated with the terminal device 130) to the server 110. After receiving the start service information, the server 110 (e.g., the processing module 520) may monitor the transportation service (e.g., monitor a timing of the transportation service) until a service transaction associated with the service request is completed.

In some embodiments, when the service transaction associated with the service request is completed, the bicycle and/or the terminal device 130 may transmit end service information (e.g., the time point when the lock 170 is locked, the destination associated with the service request, the lock identification information, the user identity associated with the terminal device 130) to the server 110. After receiving the end service information, the server 110 may stop the monitoring of the transportation service (e.g., stop the timing) and determine billing information based on the start service information and the end service information. Further, the server 110 (e.g., the transmission module 530) may transmit the billing information to the terminal device 130.

In some embodiments, when the bicycle intends to transmit the service information to the server 110, the bicycle may determine whether a connection between the bicycle and the server 110 is established. According to a result of the determination that the connection is not established, the bicycle may store the service information in a storage device (e.g., the storage module 640) in the bicycle, and when the connection is established, the bicycle may transmit the service information to the server 110.

In some embodiments, the server 110 may identify a location where the bicycle transmits the service information to the server 110 and determine a signal blind area based on the location and the destination associated with the service request. For example, if the destination of the service request is location A the bicycle or the terminal device 130 transmits the service information to the server 110 at location B, the server may determine that an area including location A and location B (or an area from location A to location B) where the communication signal may be weak and determine such area as a signal blind area. The server 110 may also determine a signal blind map based on a plurality of signal blind areas associated with a plurality of service requests. The signal blind map may be used to assist maintenance workers to carry out maintenance work.

In some embodiments, the service information may be determined by the terminal device 130. For example, after determining the lock information, the bicycle may transmit the lock information to the terminal device 130 via the wireless connection between the bicycle and the terminal device 130. The terminal device 130 may determine the service information based on the lock information and transmit the service information to the server 110.

In some embodiments, due to an accidental fault (e.g., network fault, bicycle fault, server fault), after the lock 170 is locked (i.e., the service associated with the service request is completed), the billing process may be still not terminated. In this situation, the requestor may manually end the billing process or provide a feedback associated with the fault by, for example, contacting the customer service. When the fault is solved, the server 110 may return extra fee (if any) to a user account of the requestor or provide a fee compensation (e.g., a discount coupon) to the user account.

It should be noted that the above description is merely provided for the purpose of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, one or more other optional steps (e.g., a storing step) may be added elsewhere in the exemplary process 700. In the storing step, any information and/or data (e.g., the reference unlocking password, the lock information, the service information) associated with the service request may be stored in a storage device (e.g., the storage 390) disclosed elsewhere in the present disclosure. As another example, in 780, the bicycle may transmit the service information to the terminal device 130. As a further example, when the requestor initiates the service request via the wireless connection with between the terminal device 130 and the bicycle, the terminal device 130 may obtain maintenance information (e.g., power information, time information, tire information, noise information) associated with the bicycle via the wireless connection and transmit the maintenance information included in the service request to the server 110.

FIG. 8 is a flowchart illustrating an exemplary process for switching modes of the lock according to some embodiments of the present disclosure. In some embodiments, the process 800 may be implemented as a set of instructions (e.g., an application) stored in the ROM 230 or the RAM 240. The processor 220 may execute the set of instructions and, when executing the instructions, it may be configured to perform the process 800. The operations of the illustrated process 800 presented below are intended to be illustrative. In some embodiments, the process 800 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the process 800 as illustrated in FIG. 8 and described below is not intended to be limiting.

In 810, the bicycle (e.g., a mode determination module (not shown) in the lock 170) may determine whether a first service transaction associated with a first service request is completed. For example, when the requestor stops the bicycle and locks the lock 170, the bicycle may determine that a first service transaction associated with the first service request has been completed.

In 820, according to a result of the determination that the first service transaction associated with the first service request is completed, the bicycle (e.g., the mode determination module) may set the mode of the lock 170 to a dormant mode. As used herein, the dormant mode refers to a mode in which the lock does not work (i.e., does not communicate with the server 110 and/or the terminal device 130). For example, as described in connection with FIG. 7, when the first service transaction associated with the first service request is completed, the bicycle may obtain one or more unlocking passwords which may be used for subsequent service request(s) from the server 110. After receiving the one or more unlocking passwords, the bicycle may set the mode to the dormant mode.

In 830, the bicycle (e.g., the mode determination module) may determine whether a second password associated with a second service request is obtained. As described in connection with step 730, the bicycle may obtain the second password associated with the second service request from the terminal device 130 or an input device on the bicycle.

In 840, according to a result of the determination that the second password associated with the second service request is obtained, the bicycle (e.g., the mode determination module) may set the mode of the lock 170 to a working mode. In the working mode, the bicycle may determine whether the second password is consistent with a pre-stored password in the bicycle. According to a result of the determination that the second password is consistent with the pre-stored password, the bicycle may actuate the lock 170 to unlock the bicycle.

In some embodiments, the bicycle may determine the start lock information (e.g., the time point when the lock 170 is unlocked) and determine the start service information based on the start lock information. After determining the start service information, the bicycle may set the mode of the lock 170 to the dormant mode. When the lock 170 is locked (i.e., the second service transaction associated with the second service request is completed), the bicycle may set the mode of the lock 170 back to the working mode. The bicycle may determine the end lock information (e.g., the time point when the lock 170 is locked). The bicycle may also determine the end start service information based on the end lock information. After determining the end service information, the bicycle may transmit the start service information and/or the end service information to the server 110, indicating that the second service transaction associated with the second service request is completed. The bicycle may execute the process 800 back to step 820 to set the mode of the lock 170 to the dormant mode.

In some embodiments, when the lock 170 is in the dormant mode and no next password associated with a next service request is obtained, the bicycle may set the mode of the lock 170 to the working mode at a target time point, wherein the target time point is a time point after a predetermined time interval (e.g., 30 minutes, 1 hour, 2 hours) from a time point when the mode of the lock 170 is set as the dormant mode.

It should be noted that the above description of the mode switching process is merely provided for the purpose of illustration, and not intended to limit the scope of the present disclosure. For persons having ordinary skills in the art, multiple variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications do not depart from the scope of the present disclosure. For example, step 810 and step 820 may be combined into a single step in which the bicycle may both determine whether the first service transaction associated with the first service request is completed and set the mode of the lock 170 to the dormant mode based on a result of the determination that the first service transaction associated with the first service request is completed. As another example, step 830 and step 840 may be combined into a single step in which the bicycle may both determine whether a second password associated with a second service request is obtained and set the mode of the lock 170 to the working mode based on a result of the determination that the second password associated with the second service request is obtained.

FIG. 9 is a block diagram illustrating an exemplary identification device according to some embodiments of the present disclosure. In some embodiments, the identification device 900 may be integrated into the bicycle (e.g., the lock 170). The identification device 900 may include a card sensor 902, an iris collector 903, a fingerprint reader 904, an input device 905, and/or a processing device 906.

The card sensor 902 may be configured to collect card information associated with a requestor. In some embodiments, the card sensor 902 may include a near field detector (not shown) and a magnetic card reader (not shown). When the near field detector determines that a card (e.g., a bank card, an access card, a bus card, an identity card, an identification card, an integrated circuit card) is positioned nearby the bicycle (e.g., the lock 170), the magnetic card reader may identify the card and extract the card information from the card. As used herein, “nearby” refers to that a distance between the card and the bicycle (e.g., the lock 170) is less than a distance threshold (e.g., 1 mm, 2 mm, 5 mm, 1 cm, 2 cm). The card information may include card identification information (e.g., a card serial number), a validity period, a card issuing institution, user information associated with the card (e.g., real name, ID number, telephone number), etc. In some embodiments, the card sensor 902 may include a photodiode-based scanner, a laser scanner, a CCD reader, a camera-based reader, etc. The iris collector 903 may be configured to collect iris information associated with a requestor. The iris collector 903 may include an image acquisition device (not shown), an image processing device (not shown), etc.

The fingerprint reader 904 may be configured to collect fingerprint information associated with a requestor. The fingerprint reader 904 may include an optical fingerprint sensor, a semiconductor capacitance transducer, a semiconductor thermistor sensor, a semiconductor pressure sensor, an ultrasonic sensor, a radio frequency fingerprint sensor, etc.

The input device 905 may be configured to receive an input including identification information associated with a requestor. The identification information associated with the requestor may include the card information, the iris information, the fingerprint information, and/or any other unique identification (e.g., face identification information, passport number, driving license) associated with the requestor. In some embodiments, the input device 905 may include a keyboard, a touchscreen, a voice recognition device, etc.

The processing device 906 may be configured to process the identification information associated with the requestor and determine whether the requestor has permission to use the bicycle based on the identification information. In some embodiments, the processing device 906 may obtain reference identification information from a storage device (e.g., the storage 150) disclosed elsewhere in the present disclosure and compare the identification information with the reference identification information. The reference identification information may include reference card information that has been registered with the bicycle sharing system, reference iris information that has been registered to the bicycle sharing system, reference fingerprint information that has been registered to bicycle sharing the system 100, etc.

For example, the processing device 906 may compare the card information with the reference card information and determine whether the card information is consistent with the reference card information. According to a result of the determination that the card information is consistent with the reference card information, the processing device 906 may determine that the requestor has permission to use the bicycle. As another example, the processing device 906 may compare the iris information with the reference iris information and determine whether the iris information is consistent with the reference iris information. According to a result of the determination that the iris information is consistent with the reference iris information, the processing device 906 may determine that the requestor has permission to use the bicycle. As a further example, the processing device 906 may compare the fingerprint information with the reference fingerprint information and determine whether the fingerprint information is consistent with the reference fingerprint information. According to a result of the determination that the fingerprint information is consistent with the reference fingerprint information, the processing device 906 may determine that the requestor has permission to use the bicycle. Alternatively or additionally, the identification information may be transmitted to the server 110 via the communication port 440 to be processed. The server 110 may compare the identification information with the reference information and according to a result of the determinaiton that the identification information is consistent with the reference information, the server 110 may determine that the requestor has permission to use the bicycle. The server 110 may also transmit the information indicating the requestor's permission to use the bicycle to the bicycle.

After determining that the requestor has permission to use the bicycle, the processing device 906 may generate an unlocking instruction and transmit the unlocking instruction to the control component 420. The control component 420 may actuate the lock 170 to unlock the bicycle based on the unlocking instruction.

In some embodiments, the identification device 900 may further include an encoding device (not shown) which may be used to encode the identification information. For example, the encoding device may encode the identification information as electronic signals and transmit the electronic signals to the server 110.

The modules in the identification device 900 may be connected to or communicate with each other via a wired connection or a wireless connection. The wired connection may include a metal cable, an optical cable, a hybrid cable, or the like, or any combination thereof. The wireless connection may include a Local Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a ZigBee, a Near Field Communication (NFC), or the like, or any combination thereof. Two or more of the modules may be combined into a single module, and any one of the modules may be divided into two or more units. For example, the identification device 900 may include a storage device (not shown) which may be used to store the obtained identification information and the reference identification information.

FIG. 10 is a flowchart illustrating an exemplary process for determining an unlocking instruction based on identification information according to some embodiments of the present disclosure.

In 1010, an obtaining device (e.g., the card sensor 902, the iris collector 903, the fingerprint reader 904, the input device 905) may obtain identification information associated with a requestor. As described in connection with FIG. 9, the identification information associated with the requestor may include the card information, the iris information, the fingerprint information, etc.

In 1020, the processing device 906 may analyze the identification information. In some embodiments, the processing device 906 may obtain reference identification information from a storage device (e.g., the storage 150) as described elsewhere in the present disclosure. The processing device 906 may also compare the identification information with the reference identification information. The reference identification information may include reference card information that has been registered to the bicycle sharing system, reference iris information that has been registered to the bicycle sharing system, reference fingerprint information that has been registered to the bicycle sharing system, etc. For example, the processing device 906 may compare the card information with the reference card information and determine whether the card information is consistent with the reference card information. According to a result of the determination that the card information is consistent with the reference card information, the processing device 906 may determine that the requestor has permission to use the bicycle. As another example, the processing device 906 may compare the iris information with the reference iris information and determine whether the iris information is consistent with the reference iris information. According to a result of the determination that the iris information is consistent with the reference iris information, the processing device 906 may determine that the requestor has permission to use the bicycle. As a further example, the processing device 906 may compare the fingerprint information with the reference fingerprint information and determine whether the fingerprint information is consistent with the reference fingerprint information. According to a result of the determination that the fingerprint information is consistent with the reference fingerprint information, the processing device 906 may determine that the requestor has permission to use the bicycle.

In 1030, the processing device 906 may generate an unlocking instruction based on the analysis result. The processing device 906 may transmit the unlocking instruction to the control component 420 to actuate the lock 170 to unlock the bicycle.
